This is the Model 7 universal sheath and holster spring clip. This clip design is excellent for mounting items on KYDEX and leather carry systems, and are very durable. This version is powder coated black and is common on military sheaths, holsters, and gear. The Model 7 universal holster clip is not drilled. Because of this, it is great for removable, and/or pocket-style mountings. They can also be drilled for fixed mounting with common holster mounting hardware. Any standard twist drill can be used to create mounting holes, if desired.
